Merge tag 'char-misc-5.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver fixes from Greg KH:
 "Here are a number of small driver fixes for 5.2-rc6

  Nothing major, just fixes for reported issues:
   - soundwire fixes
   - thunderbolt fixes
   - MAINTAINERS update for fpga maintainer change
   - binder bugfix
   - habanalabs 64bit pointer fix
   - documentation updates

  All of these have been in linux-next with no reported issues"

* tag 'char-misc-5.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc:
  habanalabs: use u64_to_user_ptr() for reading user pointers
  doc: fix documentation about UIO_MEM_LOGICAL using
  MAINTAINERS / Documentation: Thorsten Scherer is the successor of Gavin Schenk
  docs: fb: Add TER16x32 to the available font names
  MAINTAINERS: fpga: hand off maintainership to Moritz
  thunderbolt: Implement CIO reset correctly for Titan Ridge
  binder: fix possible UAF when freeing buffer
  thunderbolt: Make sure device runtime resume completes before taking domain lock
  soundwire: intel: set dai min and max channels correctly
  soundwire: stream: fix bad unlock balance
